Over 1.7 million acres in size, the Big Bog IBA is generally known as the Red lake Peatlands, and contains some of the most unique terrain and habitat in the United States. It is a vast, forested, boreal landscape at latitude where else where in the eastern forest in the US, boreal forest is uncommon. The area is located in north central Minnesota north and east of the Red Lake Reservoir. This IBA includes land within the Red Lake Indian Reservation along with a number of states owned Wildlife Management Areas, Scientific and Natural Areas and State Forests and Parks. At least 289 bird species are found in this area, including at least 12 species of breeding warblers. At least 110 species are major users of this habitat. Boreal forest species such as Spruce Grouse, Boreal Chickadee, Black-backed and Three-toed Woodpeckers and many species of neo-tropical warblers occur and breed in this area. The site is a major concentration point for Northern Hawk Owls and Great Gray Owls during the period November to March. The fact that some mammals and many bird species are at the southern edge of their distributional range in this IBA confers even more ecological significance to this area.
